The 4d8-(4d74f + 4d76p + 4p54d9) transitions in the spectrum of five times ionized indium (In VI)

The spectrum of five times ionized indium excited in a vacuum spark has been studied in the wavelength region 180−250 Å using a 3 m grazing incidence spectrograph. Transitions from highly excited interacting configurations 4d74f + 4d76p + 4p54d9 to the ground state 4d8 configuration were studied. 165 spectral lines were identified and 81 levels of the excited configurations were found.
